Question

m∠K=(5x+13)°. Find the measure of the complement of ∠K.


A. (167 + 5x)°
B. (77 + 5x)°
C. (77 − 5x)°
D. (167 − 5x)°

Answer 1

Answer:

Option C

Step-by-step explanation:

Sum of two angle in complement = 90

Let the other angle be a

a + 5x + 13 = 90

a = 90 - (5x + 13)

a = 90 - 5x - 13

a = 77 - 5x
